The treatment of GCTs with other non-GCT somatic elements is complex, and few data exist to direct treatment. In adolescents, central primitive neuroectodermal tumors and sarcomas have been found in teratomas.[4,5] The Italian Pediatric Germ Cell Tumor group identified 14 patients with malignant GCTs with a somatic malignancy, such as neuroblastoma or rhabdomyosarcoma, embedded in teratomas (<2% of extracranial GCTs).[6]

Source links and citations

The optimal treatment strategy for GCTs with non-GCT elements has not been determined. Separate treatments for both malignant GCTs and non-GCT elements may be required.
